Abstract
An aroma-tight cigarette pack with an outer pack (12) configured in the form of a hinge-lid box, and also with an inner pack (11) configured in the form of a sealed block with an opening aid which can be used a number of times. The opening aid has a removal opening (51) which extends in a sub-region of an inner front wall (39) and of an adjacent inner end wall (41) and is covered over by a closure label (54) with an adhesively bonding connecting periphery (55). The inner pack (11) has closure seams (37) which are designed in the form of fin seams.
Claims12
A method of producing packs for cigarettes (10), the packs comprising a dimensionally stable outer pack (12) and an inner pack (11) configured in the form of a sealed block and having an inner wrapper (14) made of preferably aroma-tight and moisture-tight, thermally sealable or cold sealable sheet material for wrapping a cigarette group (13) and having an inner collar (46) partially enclosing the cigarette group (13), wherein the inner wrapper (14) has on two mutually opposite narrow surfaces, namely on inner side walls (43, 44), edge closure seams (37, 38) configured as sealing seams in a fin seam configuration and running in the longitudinal orientation of the cigarettes (10), wherein the inner wrapper (14) has a continuous connecting seam (36) that runs transversely to the edge closure seams (37, 38) and that extends over the entire width of the inner wrapper (14), comprising the steps of:
- applying the edge closure seams (37, 38) and the continuous connecting seam (36) to the inner wrapper (14);
- after the edge closure seams (37, 38) and the continuous connecting seam (36) are applied to the inner wrapper (14), venting the inner pack (11) via venting openings (78, 92) by means of pressure being transmitted to at least one surface of the inner pack (11), wherein the venting openings (78, 92) are provided in a region outside of the contents of the inner pack (11), namely outside of a region of the cigarette group (13) and the inner collar (46);
- following venting the inner pack (11), closing the venting openings (78, 92) by applying additional sealing seams (96, 97) in the region between a respective one of the edge closure seams (37, 38) and the cigarette group (13), wherein each of the additional sealing seams (96, 97) is positioned offset relative to the respective one of the edge closure seams (37, 38);
- and
- after the additional sealing seams (96, 97) have been applied, severing edge strips (98) comprising the complete regions of the closure seams (37, 38) from the inner pack (11).
